IMPROVEMENT IN CULTIVATORSL Specification forming part of Letters Patent No. 178,4 l0, dated J une 6, 1876; application filed April 27, 1876.

To all whom it may concern:

Be it known that I, CHARLES D. CARTER, of Spring Arbor, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Cultivator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled inthe art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

The nature of my invention consists in the construction and arrangement of a cultivator, as will be hereinafter more fully set forth, and

which is fully illustrated in the accompanying I drawing.

In the construction of my cultivator I use a Wrought-iron beam, bent in or near the center, so as to form, as it were, an eye, a, and the two parts of the beam extending rearward from said eye, and then bent in proper form shovel at each end, thus making two beams, A A, of one continuous wrought-iron beam. There are no holes through this beam, but the handles and shovels are attached by separate devices, as hereinafter described.

To each of these double beams is attached a handle, B, by the following means: To the lower end of the handle is secured a curved casting, C, having a longitudinal slot, b, with enlargement b at one end. In this is inserted -a headed or grooved bolt, d, which can be moved to any point in the slot. On the two arms of the beams is placed a disk, D, having upon its upper side a concave flanged seat, in which the casting C rests, the bolt d passing through a hole in the center of the disk and down between the two arms of the beam. On the lower end of the beam is placed a washer, f, and a nut, e, screwed on the end of the bolt, thus securing the parts firmly together. The handles are thus attached without making any holes through the beams, and can be adjusted high or low, and to either sideof the beam, as required. If a third shovel is required with each beam, a small beam, E, is placed between the two arms of the beam, and a disk, G, used in place of the washer f, above mentioned, said disk having on its upper surface suitable formed with a post, J, on the back. is made tapering,

grooves, in which the beam E and both arms of the beam A fit. By then screwing up the nut e the handle, as well as the small beam E, is firmly held in its place.

The end-0f the beam back of the shovel is bent rearward, and through the same is passed a pin or axle, upon which are placed two small wheels, h h, one on each side, for the purpose of regulating the depth of the shovels in the ground, the shovels being raised or lowered on the beam or standard to vary the depth.

H represents the shovel, which is fastened to the front of a casting or shovel-block, I, This post with a triangular opening through it for the passage of the standard. At the bottom of the block I are two projections, 00 00, between which the standard fits; and at the top of the block is a series of notches, y, in either one of which the standard may be placed. By this means the shovel can be inclined to either side of the standard, and without changing the position of the point of the shovel, which is held in any position by a set-screw, is, through the end of the post J, and bearing against the back edge of the standard.

The two double beams for forming-the cultivator are connected by means of an arch, K. Each end of this arch passes through the inner ends of two plates or castings, L L, formed on their inner sides with hubs m m, through which the end of the arch passes, and which hubs are placed and meet in the eye a of the cultivator-beam. The end of the arch is then riveted or otherwise fastened.

In the center of the plates L are other hubs, n a, through which a screw or bolt, 19, is passed for fastening them together.

Between the outer ends of the plates L is pivoted a casting, P, from which the wheelspindle .9 extends outward. From this casting also projects an arm, R, in the front end of which is formed a socket for the attachment of the whiffletree S.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The slotted curved casting 0, bolt d,

disk D, with concave seat, washer f, and nut e, in combination with the handle B and beam A, substantially as and for the purposes herein set forth.

2. In combination with the two arms A A of the cultivator-beam, the auxiliary beam E, the grooved or flanged disk G, disk D, and

bolt and nut, substantially as and for the purposes herein set forth.

3. The combination, with a shovel and standard, of the block or casting I, having projections av, grooves 31, and tapering post J, with triangular slot and set-screw, substantially as and for the purposes herein set forth.

4. The combination of the plates L, having holding device R, casting P, and plates L,-

substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of April, 1876,

CHARLES D. CARTER.
